Throttle manifold JG80 21

Product Overview The Throttle manifold JG80-21 is a flagship product of Yancheng Kaifa Petroleum Machinery Co., Ltd., engineered as a High-Performance Throttle Manifold and Quality Throttle Manifold for oil and gas well pressure control. As a critical blowout prevention device, it regulates casing pressure via precise choke valve adjustment (when the blowout preventer is closed), maintaining bottom hole pressure marginally above formation pressure to block formation fluid inflow. It also enables soft well shut-in through gradual pressure release and emergency blowout relief to protect wellheads when pressure exceeds safe thresholds—essential for safe, compliant oil/gas drilling operations worldwide. Technical Specifications Model: JG80-21 Nominal Diameter: 80mm (main manifold body) Rated Working Pressure: 21MPa (stable operation under design pressure) Material: High-strength carbon steel alloy (anti-corrosion coating for harsh oilfield environments) Choke Valve Type: Manual (standa…
